: Each day I have been getting less and less pressure from the master bath shower head and spout. I am not sure of the piping in the walls, but the water pipes are those gray poly ones. I was told that I do not have the recalled fittings. All other faucets in the house are working fine. Thanks.

Darren,I would remove the shower head and see what kind of water is there. You may need to replace or clean the shower head. Terry
